Polluted air first passes through Alen's washable Pre-Filter to capture large particles. In the second layer, air moves through a unique, electrostatically charged HEPA style material that captures airborne pollutants. Alen's anti-microbial Silver-Ion threads are woven into the HEPA style material, protecting the filter from bacteria* and microbes. In the final layer, clean air passes through a layer of Alen's Activated Carbon, reducing light odors and chemicals.

*Tests demonstrate a 99.99% kill rate on E. Coli and Staph Bacteria.
